The assessment of usability of pain medical device by physiatrists and physiotherapists: A Delphi survey

When developing a new medical device, it is essential to assess the usability of such a device through various stakeholders. This study assessed the usability of pain medical devices through a Delphi survey administered to physiatrists and physiotherapists. A Delphi survey was conducted on the problems and improvements in hardware and software for a panel consisting of 10 physiatrists and 10 physiotherapists. A total of 3 rounds of surveys were conducted, and the third round of survey was confirmed through a Likert scale (1 = strongly agree to 5 = strongly disagree). The 2 groups generally had a common perception of the problems and improvements in pain medical devices. However, the physiatrist group mostly identified problems such as linking patient information, whereas the physiotherapist group deemed hardware problems such as device weight or connection cables as being more important (mean [standard deviation]; physiatrist, hardware 2.90 [0.93], software 2.28 [0.91] / physiotherapist, hardware 3.04 [0.84], software 3.03 [1.13]). To date, analysis has not been conducted by dividing the focus of various stakeholders using pain medical devices. The difference in view of the usability of these 2 stakeholder groups should be considered when improving the hardware or software of pain medical devices in the future. Further research is warranted to investigate other stakeholders such as patients and device developers to improve the devices.
